Elite / PowrLiner part 2342943 is an outlet valve housing used in the high‑pressure fluid section of compatible airless sprayers and line stripers. It houses the outlet check valve and directs pressurized paint from the pump to the hose and gun. Replacing a worn or damaged housing restores proper flow, pressure consistency, and system reliability.

The Elite / PowrLiner 2342943 Outlet Valve Housing is an OEM replacement component that serves as the high‑pressure discharge manifold for the pump. It houses the outlet check valve (ball, spring, and seat) and directs pressurized paint from the pump cylinder to the hose, gun, and spray tip.
Over time, the outlet valve housing can develop cracks, wear from pressure cycling, or corrosion from chemical exposure. A compromised housing may cause pressure loss, erratic spray performance, or external leaks. Replacing with this genuine housing restores proper outlet flow, consistent pressure, and safe operation.
| Pressure delivery | Directs high‑pressure paint from pump to the hose and gun |
|---|---|
| Check valve support | Houses the outlet valve (seat, ball, spring) that prevents backflow |
| Pressure stabilization | Helps maintain smooth, consistent flow during spray operations |
| Pressure loss / surging | Inconsistent pressure, pulsation, or inability to maintain set pressure |
|---|---|
| External leakage | Paint seeping or spraying from the housing area |
| Visible damage | Cracks, warped mounting surface, or stripped threads |
| Outlet valve failure | Repeated ball/seat wear or contamination that cannot be resolved without housing replacement |
Elite / PowrLiner part 2342943 is a direct replacement outlet valve housing for the following models:
| Brand / Model | Application |
|---|---|
| Elite 5500 | Outlet valve housing assembly |
| PowrLiner 4500 | Outlet valve housing assembly |
| PowrLiner 5500 | Outlet valve housing assembly |
Replacing the housing is the ideal time to install a new outlet valve kit for full pump performance.
Use new seals to prevent leaks at the housing‑to‑pump interface.
If the housing includes a pressure port, inspect the transducer or gauge for accuracy and damage.
